Click here for the West Nile Seasonal August 7th, 2017

Based on all data available August 7th, we expect to see 65 cases in SD in 2017. This forecast is up from last week's predictions. There was a large increase in the mosquito infection rate, and this may mean that cases will be later than expected in 2017. All our data still imply an average year, but an average year means substantial disease transmission.
